Answer 1

The area is the length times width or A=lw . The length is 4 times the width so l=4w . We substitute 4w for l and solve for the width. Then we plug it in for the length.

• A=lw=4w∗w=4w2=46

• 2w=46−−√→w=46√2

• l=4w=4∗46√2=246−−√

Now just put those results into a calculator. The width is 3.39 inches and the length is 13.56 inches.
